With the popularity of personal mobile phones and the recent increase in the spread of smartphones and tablet PCs, the use of radio waves for calls and wireless Internet is increasing rapidly. In addition, the demands of customers who want to use the telephone and the Internet anytime, anywhere, and the demand for the communication speed and call quality are increasing.

In particular, customers are demanding the appropriate call quality not only outdoors but also indoors such as buildings, even in shadowed areas where distances from existing base stations and mobile communication repeaters are not well communicated by the terrain.

To meet the demands of these customers, each service provider is installing additional indoor antennas, base stations and mobile communication repeaters in shaded areas. In addition, the terminal used by customers may vary in the frequency band used. For example, terminals used by customers can support various wireless communication methods as well as mobile communication based on large base stations such as WAN, WIFI, and near field wireless. Typically, indoor antennas are installed in proportion to the size of the building.

However, it is impossible to know the distribution and real-time usage of users using various wireless communication methods in a building, so it is not known whether an appropriate number of indoor antennas are installed in the building.

In addition, if the building is a multi-storey building, the user's distribution and real-time usage may be different for each floor. However, since indoor antennas are installed without considering this, it is difficult to effectively manage communication traffic in the building.
